It disables git-gc --auto when you are running Linux and you are on battery.

+#!/bin/sh
+#
+# An example hook script to verify if you are on battery, in case you
+# are running Linux. Called by git-gc --auto with no arguments. The hook
+# should exit with non-zero status after issuing an appropriate message
+# if it wants to stop the auto repacking.
+#
+# This hook is stored in the contrib/hooks directory. Your distribution
+# will have put this somewhere standard. You should make this script
+# executable then link to it in the repository you would like to use it
+# in.
+#
+# For example, if the hook is stored in
+# /usr/share/git-core/contrib/hooks/pre-auto-gc-battery:
+#
+# chmod a+x pre-auto-gc-battery
+# cd /path/to/your/repository.git
+# ln -sf /usr/share/git-core/contrib/hooks/pre-auto-gc-battery \
+#	hooks/pre-auto-gc-battery
